I am currently trying to get in touch with vxlan. For this I wanted to setup a VXLAN on two of my boxes and connect them via VXLAN.
I have the following /etc/network/interfaces configuration on Host1:
auto lo
iface lo inet loopback
iface enp2s0f1 inet manual
auto vmbr0
iface vmbr0 inet static
address xxx.xxx.xxx.12
netmask 255.255.255.0
gateway xxx.xxx.xxx.xxx
bridge_ports enp2s0f1
bridge_stp off
bridge_fd 0
auto enp2s0f0
iface enp2s0f0 inet static
address 10.0.0.12
netmask 255.255.0.0
auto vx0
iface vx0 inet static
mtu 1600
pre-up ip link add vx0 type vxlan id 10 group 238.182.226.153 dev enp2s0f1 || true
up ip link set vx0 up
down ip link set vx0 down
post-down ip link del vx0 || true
address 10.1.1.12
netmask 255.255.255.0
The configuration on my second host looks like this:
auto lo
iface lo inet loopback
iface enp2s0f1 inet manual
auto vmbr0
iface vmbr0 inet static
address xxx.xxx.xxx.13
netmask 255.255.255.0
gateway xxx.xxx.xxx.254
bridge_ports enp2s0f1
bridge_stp off
bridge_fd 0
auto enp2s0f0
iface enp2s0f0 inet static
address 10.0.0.13
netmask 255.255.0.0
auto vx0
iface vx0 inet static
mtu 1600
pre-up ip link add vx0 type vxlan id 10 group 238.182.226.153 dev enp2s0f1 || true
up ip link set vx0 up
down ip link set vx0 down
post-down ip link del vx0 || true
address 10.1.1.13
netmask 255.255.255.0
The multicast address is working fine (I have tested it via iperf). With wireshark I can see that Host1 sends ARP Request to the broadcast address and is searching for Host2 / 10.1.1.13 but there is no answer.. any idea?
Also: When I try to restart networking it throws an error, the interface exists but it isn't up. But I can set it up manually.
